Nintendo Sonic Riders Zero Gravity Wii

Gameplay in Zero Gravity is largely similar to its predecessor, with characters racing on different types of hovercraft called "Extreme Gear". In addition to the mechanics from the previous game, such as the trick system, Zero Gravity adds a new gameplay system based around gravity that replaces the predecessor's  system. During the race, performing tricks and other actions will increase a character's Gravity Points, or GP. If players have accrued enough GP, they can perform one of two maneuvers. A Gravity Dive will create a small black hole that points gravity forward down the track, giving the player a powerful free-fall boost that is further augmented by striking objects in the vicinity that the hole displaces, such as cars or signs. Alternatively, Gravity Control will alter the gravity of the course, allowing players to reach otherwise-inaccessible areas and shortcuts. Players can also use Gravity Control to more easily maneuver around sharp corners.

Building on the upgrade system from Sonic Riders, Zero Gravity features a new system called "Gear Change". Once players gain a certain number of rings during a race, they can choose to activate one of their Gear Parts. Gear Parts are predetermined based on the racer's equipped Extreme Gear, and will grant bonuses when activated, such as increasing a character's top speed or
